Influence of the steeped spillway slope on the number of optimal steps
In the present study 54 step spillways make of ple Glass, 5 discharges (10, 20, 30, 40 and 50 l/s/m) and 3 slopes, z=1.7 , z=2 and z=2.5 (totally 275 experiments were conducted). Finding of the present study are as follows: 1- Performed modeling observations revealed that the relative energy dissipa...

description | In the present study 54 step spillways make of ple Glass, 5 discharges (10, 20, 30, 40 and 50 l/s/m) and 3 slopes, z=1.7 , z=2 and z=2.5 (totally 275 experiments were conducted). Finding of the present study are as follows: 1- Performed modeling observations revealed that the relative energy dissipation along with spillway will be decreased with increasing discharge. 2- It is shown that energy dissipation is increase with increasing step numbers, but energy dissipation will be stopped in a certain number of steps. 3- According to presented study, optimal number of steps base on different values of yc/h and Froude Number is determined for the maximum energy dissipation. It is shown that optimal number of steps is affected by slope of spillway. Increasing spillway slope causes more energy dissipation. |
